for its object the production of a shingle which will produce averypleasmg appearance'on the roof and will very' effectively cover and protect the roof. A fnrther object of the invention is to shape the shingle so that theabove mentioned ob'ects will be obtained and theshingles may cut from i I L strips without any waste.- Other objects of the invention willbe apparent from a consideration of the accompanying drawings and the following descri tion thereof:

Ofthe drawings ig.{1 is a plan-view of i a strip oi shingle material showing how the shingles are cut from a strip; Fig. 2 is a plan view of a portion of a roof with the shingles assembled thereon; Fig. 3 is a plan view of the individual shingles shown in Figs. 1 and 2;; Fig. 4 is a' plan view. of a slightly'modified shingle; Fig. 5 is 'a' plan view of a strip showing the manner in which another modi- 'fied form of shingle is cut therefrom; F

is a plan view of'theshingles of Fig. 5 w en assembled; Fi 7 is a plan view of an inedge viewof the same.

dividual shing eof Fig.6; Fig. 8 is an edge view of the same; Fig. 9 is a plan View of another .form of shingle; and.Fig.10-1s.an

. The shingles illustrated by Figs. 1 to 3 comprise the body portions 10 having lugs 11 and 12 and edges 13. These edges may be sha ed 7 as shown or otherwise shaped so as toa ect theappearance of thereof, as they are the lower edgesiof the lap portion 14 which is exposed below the upper layer of shingles. The shingles also have slits 15, and 16 when desired, and notches 19. As will be-seen by an inspection of Fig. 2, the shingles are laid in strips, running longitudinally on the roof,

jacent shingle and the slit 16 co-acting with diately beneath the edge 17 of the righthand and theindividual shingles in-the strips form rows running up and down the roof.

But the shingles of one may be staggered with reference to those of an adjacent strip if desired. a

The strips are formed by connecting indi vidual shingles, the lug 12 of a left hand shingle passing under the lower edge of the ad'- th notch 19 so that the'edge 18 of the left hand .shingle registers with andis immeshingle. This arrangement is repeated with the edges of the other adjacent shingles in the strip, and in this'w'ay the individual shingles are formed into strips which are held together by. the coactionv of the slits and notches.

Thestrips are thus independent ci i -eachother and may be laid on the roof substantially the same as ordinary strip shingles: Each strip may lap over the ad acent underlying strip so .far as may be desired. In this instanc'e,'. v

however, I prefer to have the shingles of the overyling strip lap between the strips-is provided. This ,iin-

having an interlockingslit and notch, the

interlocking canbe made more'quiokly and is more effective. The notch .allowslthe slit I to be quickly" placed, while the slit holds the 1 two shingles firmly in their relative positions. .75 -Wi th two notches, the connectionwould be loose and the shingles-would easilyishift more or less out of their relative positions. I In laying the shingles, they are often lookedtpi gether in rows, and the rows are then shifted into position with reference to adjoining rows, and it is'important that there. be no relative shifting of the individualrshingles', i

It will be understood that the looking together of the lower edges oftheshingles as explained prevents these 'exposed edges 'or corners fromwarping or blowing upwardly.

The edges 1-3 may be bowed upwardly instead" of downwardly if desired and the particular form of these edges is not a-material part of the invention; .When the edges are bowed upwardly the slits 15 are used and they coact ,7 with notches or slits on the same side but" at e other e jacent shingle 4 illustrates t" odifiedf forfii 05 .of shin 1e in which the e go 18 curvedtocore I to the curve of theexposed sa of the adjacent overlying shingleand. 1 1

respon registers with and is immediately beneath the portion 22 shingle.

I The type of shingle illustrated 1 "Figs. 6 f to 8 is similar in general to that of igs.. 1 to 3, but is substantially double length and-has I the curved edges 23 and 24 alternating up and;

down as indicated. The manner. o'f ,jeutting' on the underlying strip until the edges '18 of the overl I ing strip register with the edges 20 of t e 65" underlying strip. In this way-three shin gle thicknesses are provided at this point, and a more pronounced line of demarkation proves the appearance of the roof." Also, by 70" of the adjacent1 overlying 10o Figs.'5 to 8 transverse ridges 25, 26, and 27 are formed in 'the shinfgles. These ridges add to the appearance ridge of each shingle registers with the ridge of the-adjacent underlying shingle-and thus -:forms what appears as a continuous ridge'run-.-

' r -but having a tongue pro ect on from each cor- 'ning up and down the roof;

Figs. Sand illustrate a sli htly modified form of shingle in which the edges 30 and 31 bow upwardly on the roof and the ridges 32 and 33 are wide and flat. In thiscase each end of these ridges register with a ridge on:

the adjacent overlying or underlyingshingle.

The ridges 27 and 33 are positionedimmediately at one side of;'the slits on the lower edges of the shin les and this provides a he lugsto slip under when the corners are being locked together'as the shingles are laid. j A

I claim as my invention:

1. A shingle having a lug extending from the corner of one edge thereof, and a slit-ex'-, tendin part way between said lug and the,"

- body 0 the shingle on the side of the lug most remote irom the edge, and a second slitnin the.

said edge near. the opposite end of the shin le and adapted to coact with the lug on an ad a-;

cent shingle, and a .raisedportion onthe shingle immediately at one side of said second slit.

a liig extending from the corner of one edge thereof, and -a" slit extending part way be-- tween said lug and the body of the shingle on the side .ofthe In most remote from the edge, a second slitin tll site end oftheshingle andadapted to enacte saidedge near the oppowith the lug on an adjacent shingle, and a second lug extending from the corner nearest to saidfirst mentioned corner.

3. A shingle of general rectangular shape, but having a tongue rojection from each corner of one end, one o the said tongues havthe roof, and the ridges: 27 prevent rain from driving under the '28 of the adjacent right hand-shingles. he

2. A rectangularly-shaped shingle having.

mg a slit therein, as slit extending inwardly of said tongue from the side thereof most re mote from the adjacent side of theshingle,

- and the said side of the shingle having a notch therein adjacent theother end 'of said side'and projcctingiinwardly from said side e dge,-the

said tongue of the shingle being adapted to lieunder the end of another similar shingle with the notch ofwiththe slit interlocking the other similar shingle,

1i. A shingle of general rectangular shape,

iner of one end one of the-said tongues hav lar shingle with theslitof one shingle interlocking with the notch of the other shingle,

and the inner, end s of the said slit and notch substantially registering.

"5. A shingle having a" lag extending from the corner of one ed e thereof, and a slit extending between sai lug and the body of the shingle, and a notch in the adjacent edge near the frexnote end thereof,- said notch being adapted to coact withthe slit onan adjacent shingle, and a raised portion extending across said shingle immediately at one side of said vnotch. 6. A rectangularly-shaped shingle having a lug extending from a corner of one end thereof, and a slit extending part way between said lug and the body of; the shingle on the side of the lug most remote'from the shingle side, said'shinglehaving a notch in its said side near the oppositeend of the shingle, said notch being adapted ,to coact with the slit in an adjacent shingle, and a secondlug extending' from the other corner of said first mentioned end and adapted to lie under the slitted lug of another similar shingle.
